[PATCH] Check for valid branch when building

[Nelson Castillo]

From: Nelson Castillo <arhuaco at freaks-unidos.net>

Make sure we are in a valid branch to avoid
OM developers some trouble.

* Print a nice message if we are not in a valid branch.

Please feel free to edit the error message if you think it is
not clear enough.
